Unity 5 editor in Windows 64 vs 32 bit

Hi
Can anyone tell me if there are separate versions of the Unity 5 editor for both 32 and 64 bit windows?

Yes, there are two separate versions for Unity Editor for 32-bit and 64-bit.

On this Download Unity page check under ‘Additional Downloads’ where you can find the option to download either 32-bit or 64-bit editor.

There is no option (anymore) for this
